**Possible Answers:**

**Correct answer:**

### Example Question #279 : Plane Geometry

A triangle has an area of 36 in.^{2}. if its base is 6 in., what is its height?

**Possible Answers:**

**Correct answer:**

To find the height of the triangle, you must need to plug in what you know (the area and the base of the triangle) into the formula to find the area of the triangle:

Now that you plugged in the area and the base into the formula to find the area of a triangle, you can solve for the height:

Multiply both sides by 2 (the reciprocal of 1/2) to get rid of the fraction

Divide both sides by 6 to find the height

Remember that is the same as

### Example Question #1 : How To Find The Area Of A Triangle

so

### Example Question #3 : How To Find The Area Of A Triangle

A triangle has a base of 7 and a height of 4. What is the area of the triangle?

**Possible Answers:**

None of these

**Correct answer:**

The area of a triangle is found by multiplying the base times the height, divided by 2.

Plugging in the appropriate values for this equation gives us:

This reduces to:

This is equal to 14, the correct answer.

### Example Question #4 : How To Find The Area Of A Triangle

A triangle has a base of 8 inches and a height of 4 inches. What is the area in square inches?

**Possible Answers:**

**Correct answer:**

The area of a triangle can be calculated using this formula:

When inputting the base and height information, the equation looks like this:

### Example Question #1 : How To Find The Area Of A Triangle

The area of a triangle is 12 square inches. It has a height of 4 inches. What is the triangle's base, in inches?

**Possible Answers:**

**Correct answer:**

The area of a triangle is:

Given that the area is 12 and the base is 4, this gives us:

This reduces to:

### Example Question #6 : How To Find The Area Of A Triangle

If a triangle has a base of 1 foot, and a height of half a foot, what is the area in square inches?

**Possible Answers:**

**Correct answer:**

The area of a triangle is found by multiplying the base times the height, divided by 2.

Since we are looking for the area in inches, we must convert the base and height to inches, from feet.

This gives us a base of 6 inches and a height of 12 inches. Plug these values into the area equation and solve.
